What happened to the reference marks for the air pointer?


Gotta have faith Rob, a smear of light oil or grease on any surface you don't want the paint to stick to before you paint. :) And the name plates were covered to protect from sandblasting.

That stuff is easy, just time consuming. Next is the pot, and the bushing removal. Lots of fun there. I'm sure I'll be hitting you on PM before long. You have a great deal more experience with them.

I wouldn't get rid of my 350. I might put it in a rental property that my nephew occupies.

Not really everything is new on the 350 the 520 will need new parts motor fan bushing thrust washer pot bushing auger bushing shaft coupler shaft sleeve pot gaskets
water coil gasket both door gaskets change gear box oil base panels gaskets sear pin cotter pins for shaft coupler and pot auger bin auger and tubes tube coupler base ring for pot auger tube if you did not get them with it. New parts add up quick and there not cheap.

Maybe a few pot grates if any are warp or cracked Paint and time .

You are gaining 10 gals capacity of water in boiler 5.8 sq ft of heating surface with a 520 .

Heating surface on 350 22.5 sq ft . heating surface on 520 28.3 sq ft .
being both are running s-20 stokers the feed rate will be the same if both have the same size gear box on them .

I don't think you understand the reason for the 520 change. My 350 has been nothing but spectacular. It looks and operates great. I'm very pleased with it. The 520 is just a project for me. Need a change from refurb'ing the stoker stoves. I want to rebuild it and enjoy my hard work for years. I have not needed to even work the 350 hard, 4 teeth winter and summer. It is able to keep up at all times for me. It is a great boiler, very pleased with the investment. Just looking to understand the EFM's better by rebuilding one. It is stress relief for me to work in the shop.

The air chamber in the first picture with the large fines cleanout and the old style gooseneck is an old one...early 50's? Make sure that cleanout plate is not warped.
